I am guessing storing tires with dirt on them draws the moisture/oils out of the rubber. Good discussion, I always hated cleaning tires, they just get dirty again anywayz. I just do it cause I get bored and don't want to work on my car. Lol. I can ask around and see what the best tire care is and proper storage.

I think storing tires dirty does more to dry them out then air exposure.

I clean my tires after each race weekend and store them back in the AKA bags. When I need them they'll be in the same condition they were after I washed them.

You can leave tires out for a while without any negative effects. For instance 1 set is always left out for putting on the vehicle as long as their clean it doesnt seem to be a problem. BUT leave them dirty in your pit box for a couple weeks and there will be a noticeable difference.

I think the best preservative is to put them in bags after washing with mild soap. I guess I'm not sold on "moisturizing" tires.

using armor all (moisturizer) on your car tires results in a worse condition that if you simply wash them in regards to dryness.
Upon further review, I think you're onto something here. Maybe it's not that we're keeping the air out so much as we're keeping the 'gases' in.

That makes it kinda hard to get at them though when you need a new set for the amain-plus I don't have access to a rocket ship

Cleaning tires is right up there with painting bodies and glueing tires for my least favorite things to do in RC racing. But it does make sense, prolonged dirt exposure on tire rubber, guess I'll have to start getting the dirt off

Good thread!

Cleaning tires isn't all that bad, when the right stuff is used. I get as much dirt off as I can via hand the I use my tire tub. it's just two stiff brissel brushes glued down in a plastic bowl I stole from my girlfriend. Just simply put in water to the tip of the brushes. And start cleaning.

Now I do think rubber can go bad, but I have sets of tires I've had for a few months and they're the same durometer as brand new rubber. I think sun (UV rays) is more an enemy to tire rubber than air. Store them some place dark and out of direct sunlight. Just my $.02.
AZ, 1 point you may be missing is this.. Even though the tires in a zip-loc bag are exposed to air, it is a limited amount of air. IE it can't escape, and new air is not allowed in until reopened. THe air in the bag can only contaminate the rubber so much then it is essentially sterile (for lack of a better word). While if the tires are left in the open unsealed then the rubber continues to degrade because the air is constantly being replaced.. Vaccum sealing might be the next wave of RC tire storage, but I think only the anal retentive among us will go that far..

I hear you, makes sense for sure. I'm not saying ziplocing tires doesn't do anything, it definitely helps some which is why tires are shipped in sealed bags.

I might try vacuum saving some tires just for S&G. I'm curious to see what effects the vacuum would have on the foam after a week or two (probably none, but could be interesting).

I use wd40 for old tires, and it usually brings them back to life. The oil compound dries off making the tires feel hard. Spraying something like wd40 helps re-moisturize the oil. You will notice that old tires will soak up the wd40 rather fast.

sun and oxygen deteriorate most materials.

don't use chemicals (moisturizers) unless they're already on their way out.

just wash, dry, store (ziploc, out of uv), run, repeat...

This the last time I hear about Simple Green without owning it. I can't find it anywhere though! I'll see about Wallmart tomorrow...
